This system is set up with ten 10 gallon aquariums. We added hot tap water to the new tanks. When the water cooled down we added Instant Ocean and turned on the airlifts. We added the three types of dried Grunge mix to each tank.

TYPE 1. sun dried grunge from 125 gallon reef tank. We filled these 2 tanks each time they dried to a crust. We filled them three timeswith tap water.
TYPE 2. These bags of shells and gravel came from Kona. It was from the paths between the clam tanks.
TYPE 3. These bags are full of Grunge Lite™ that was dried for 4 years.

These tanks will be set up for the Summer. When they are ready we will allow them to dry in the Sun.
